You mean glycogenolysis, right? I don't think epinephrine has a direct effect on glycolysis other than to stimulate the production of glucose from glycogen.

Beta adrenergic stimulation activates adenyl cyclase which increases the levels of cAMP, which activates cAMP-dependent kinase, that phosphorylates (activates) phosphorylase kinase, which in turn phosphorylates (activates) glycogen phosphorylase, which degrades glycogen, releasing Glu1P. I guess it's part of the "flight or fight" response because it would supply glucose from stored depots.

thus glucose-6-phosphate will get high in the cell inhibiting hexo/glucokinase and activating the glycolysis pathway --> thus less glucose is imported into the cell. In this way it seems that epinephrine inhibits the fight-flight response.
